Context

About me and my background
- Professor of Transport Data Science at University of Leeds
- Focus on open, reproducible transport planning tools
- Worked in Active Travel England to build data and digital capacity
What I’ll be talking about today: open, reproducible, internationally-scalable transport tools
How this aligns with GREENTRAVEL project’s aims and themes

Thank you for the invitation to speak at this networking event on active, sustainable and green urban mobility at the Finnish Embassy.

I’m particularly excited to be here because of the strong alignment between my work on open transport planning tools and the GREENTRAVEL project’s focus on:

Greenery and green infrastructure in urban environments
Active travel promotion and planning
Exposure-aware routing that considers air quality and environmental factors
Multi-city analysis to enable international comparisons and learning

These themes run through everything I’ll be presenting today, and I hope we can find opportunities to collaborate and share knowledge across our projects.

What I’ll be covering today includes:

Why open and future-proof?
Scalable tools and case studies (UK, Portugal, international)
Opportunities to connect with GREENTRAVEL and partners

Why open access beyond open source?

“Open access goes beyond open source … users are encouraged to view and edit the source code, with measures taken to make it more user-friendly.”

Communities of practice

Open source books have 80+ contributors
Technical solutions are only as good as the community using (and contributing to) them
Share datasets, reproducible examples
Pilot features, report bugs, contribute docs

Example: plan.activetravelengland.gov.uk

Reproducible research in practice

Fully reproducible pipelines improve trust, reuse and scale
Example: spanishoddata package and paper now part of rOpenSpain community

Network Planning Tool for Scotland (npts.scot)

Discover and prioritise active travel networks at scale
Open data, transparent methods, web UI for planners and the public
National estimates of road traffic volumes and cycling Level of Service

International portability by design

Shared, open building blocks (data, code, methods)
Modular tools adapted from UK to other cities/regions
Aligns with GREENTRAVEL’s multi-city analyses and exposure-aware routing

Ideas for collaboration

TRACE: scalable, low-cost active travel counts

SchoolRoutes: safer, greener routes to school

NetGen: crowd-informed network generation; “the crowd is the territory” (Anderson et al. 2018)
